The following table summarizes the results of a study on SAT prep courses, comparing SAT scores of students in a private preparation class, a high school preparation class, and no preparation class. Use the information from the table to answer the remaining questions. Treatment Number of Observations Sample Mean Sum of Squares (SS) Private prep class 50 680 220,500.00 High school prep class 50 650 229,320.00 No prep class 50 635 251,370.00 Using the data provided, complete the partial ANOVA summary table that.follows. (Hint: T, the treatment total, can be calculated as the sample mean times the number of observations. G, the grand total, can be calculated from the values of T once you have calculated them.) Source Sum of Squares (SS) df Mean Square (MS) Between treatments Within treatments ANOVA summary tables typically have a "Total" row not included in the partial table you just completed. Which of the following is a possible reason for including this row? The SS total is used in the calculation of the F test statistic. The MStotal is used in the calculation of the F test statistic. The SS total is sometimes easier to calculate than SS between Since SS within + SSbetween == SStotal, you can use SStotal to calculate SSbetween. The total sums of squares is the sometimes called the "error term."
